Intangir has more HP than the Ultima Weapon and many end-game enemies. It absorbs all eight elements, and it can easily KO the party in one round unless they are at a high level.

The Intangir enters the battle with the Invisible status. The only way to remove Invisible is to strike the Intangir with a spell. When damaged, the Intangir will use the powerful enemy spell version of Meteor, even if transformed into an Imp. Non-damaging spells like Sleep or Stop can prevent this.

The Intangir will reapply the Invisible status shortly after attacking with Meteor.

If the Intangir wakes up with 1280 HP or less, it will flee. If slain (except through Doom, which prevents a dying animation), it will use Meteor on whoever slays it as a final attack

Since Intangir has a lot of HP, players can exploit the Vanish-Doom bug or the MuRage to defeat it in the SNES and PS versions. This does not work in the Advance and subsequent releases.

A good way to defeat it without the aforementioned bug or Rage, is to have the characters equip Hermes Sandals and cast Stop on it while it is invisible, and then use physical attacks. Using Relm's Sketch while having Strago in the party allows him to learn the TravelerLore Which Strago can use depending on how many steps the player has taken in the game.

Players can also use the characters special abilities, have Gau use "Stray Cat" Rage for the "Cat Scratch" attack, Cyan use "Bushido" Fang or Flurry, Mog use the dance "Earth Blues" which randomly casts "Rock Slide", Setzer can use "Slots", Sabin use his "Blitz" Raging Fist or Meteor Strike, Edgar use his "Tools" Drill or Chainsaw. All of which deals non elemental damage.

Another way to defeat it in the Advance and following releases, is to use the psycho Cyan bug. The player must first kill off Cyan in the Intangir battle, and revive him, then use another character to cast Cura on him to recover his HP (at least above 1,000). Cyan should then use the SkyBushido, and someone else must cast Imp on Cyan. Sky should remove Intangir's Invisible status without invoking Meteor, and Cyan should immediately begin attacking once he is in Imp status. For best results, Cyan should not be equipped with a weapon that deals elemental damage, and use the Sniper Eye relic to ensure his attacks will always hit. The Psycho Cyan Bug has been fixed in the iOS, Android and Steam version.

A third way to defeat it is to use the Confuse-Smoke Bomb glitch. The player should cast Confuse on a party member, and while the animation is running have them use a Smoke Bomb. They will use the Smoke Bomb on Intangir. Intangir uses his final Meteor, usually killing the person who used the Smoke Bomb. The Confuse-Smoke Bomb glitch has been fixed in the iOS, Android and Steam version.

A fourth strategy to defeating Intangir is Setzer'sSlot ability: three 7s will cast a modified version of Death that will kill Intangir. To ensure triple 7's the player should use Echo Screen with another character before using Slot. To guarantee getting triple 7's while playing the Slots, the player should pause and look at the next icon (the icon at the top of the reel), and if it's a 7 quickly unpause while tapping to select it, and repeat this two more times.
